小型高速柴油机常发生烧机油的故障,烧机油的原因很多,可以用下述方法检查,先拆下气缸盖,然后盘动飞轮,通过仔细观察活塞在气缸体内的位置和运动情况来分析烧机油的原因,往往有以下几种现象: 1.活塞在气缸体内的位置歪斜,头部间隙一边大,一边小。一是由于装配时,气缸套轴线与曲轴箱气缸孔轴线不重合所致。引起偏移的原因常是气缸套与曲轴箱接触面不平,如离子氮化后,气缸体的下端面有熔化的铝馏,或者是曲轴箱气缸孔表面不平有凸起, Small high-speed diesel engine often burn oil failure, burning oil for many reasons, you can check the following methods, first remove the cylinder head, and then disk flywheel, by carefully observing the piston in the cylinder body position and movement analysis of burning oil Of the reasons, there are often the following phenomena: 1. Pistons in the cylinder body position skewed, while the head gap side, while small. First, due to the assembly, the cylinder sleeve axis and crankcase cylinder bore axis do not coincide. The cause of offset is often uneven contact surface of the cylinder liner and the crankcase, such as ion nitriding, the lower end of the cylinder block has melted aluminum distillation, or crankcase cylinder bore uneven surface with projections,
